A natural phenomenon that typically influences climate over a period of one to two years is sulfur-rich violent volcanic eruption.
Without any doubt, the most plentiful volcanic gas from a volcanic eruption is water vapor, which is non-dangerous.
Nevertheless, notable volumes of carbon dioxide, sulfur dioxide, hydrogen sulfide as well as hydrogen halides can also be released from volcanic eruptions. This natural phenomenon generally influences climate over a period of one to two years.
The sulfuric acid creates a mist of minute droplets in the stratosphere that reflects the incoming solar radiation, an thus is responsible for cooling of the Earth's surface.
These droplets can stay in the stratosphere for about three years, circulating all over through winds and resulting in consequential cooling all over the world.

The correct sequence of these events (origin of mitochondria, origin of multicellular eukaryotes, origin of chloroplasts, origin of cyanobacteria, origin of fungal-plant symbioses), from earliest to most recent, in the evolution of life on earth is 4, 3, 1, 2, 5.
The transition to eukaryotic cells seems to have taken place in the Proterozoic Era, around 1.2 to 1.5 billion years ago. Nevertheless, the latest genetic studies propose the divergence of eukaryotes from prokaryotes nearer to 2 billion years ago.
Margulis suggested the mechanism of endosymbiosis, to describe the origin of mitochondria as well as chloroplasts from persistent living prokaryotes. In accordance with this idea, a bigger prokaryote engulfed or enveloped a smaller prokaryote around 1.5 billion to 700 million years ago.

If she's learning about like how she was made its best to look at books with the right information.
If its like to help her figure out who she is as a person then she should maybe take a day to go out to a quiet place like a nature trail and think about it.
